Predictive vs Comparative CAE

Are you trying to determine whether a part is going to be strong enough for its application? Or are you just looking to see if the latest design is better than the previous design? Do you have accurate loads and material data? What does all this even matter? Read on and find out more about how these things all affect the type of CAE analysis you should be performing... Ask Yourself: When performing (or engaging someone else to perform) a CAE analysis, you have to first decide on a few key points including: what you're trying to achieve the quality of the input information you have available the required accuracy of the results your budget (time and/or dollar) for the analysis The answers to these questions will help determine the best approach to meet your needs and set your expectations for the analysis outcomes.

Here at Bremar, we label these Predictive and Comparative Approaches respectively, and there are some notable differences between the two
